A Fourth Dimensional Bong
Hit is just like every other bong
hit, with the difference being as follows:- <A> you haven't slept in 4 days, <B> someone has packed it with hash crumbs or
oil without your knowledge, <C> you only smoke spliffs and you've been peer pressured into having a
hit from a bong, <D> You've only just been able to get some
green, but have had to go without for a long time (if you're a daily smoker).
Generally it is marked by a vivid blue exhale that lasts several breaths, and many coughs and splutters. Probably the cause of the term "Young Lung".
"...so one time I had this Fourth Dimensional Bong
Hit and coughed so hard that my room mates found me face down in a
pool of my own vommit... Luckily I didn't spill the bong
water though..."
